MOUNTING THE TERMINAL BOARD
1. Remove and clean any drywall debris or dust from the
rough-in before beginning installation.
2. Refer to Figure 1. Locate the terminal board in the left
rear section of the rough-in frame.
3. Use four (4) Nº 6 x 3 ⁄
8
“ screws supplied to secure the
terminal board to the rough-in frame.
4. Make certain the lower right-hand screw is secure and
snug against the ground lug which covers the mounting
hole in the terminal board. Do not bend ground lug.
Make sure it is positioned between the screw and
terminal board.
CONNECTING THE REMOTE WIRING
1. Dress all remote wiring through the rectangular holes
in the upper right and left sides of the rough-in frame.
All wiring connections are made to the master station’s
terminal board.
2. Refer to Figure 2. Connect the IW-6 cable from each
remote to the appropriate set of terminal screws at the
master station’s terminal board. When connecting the
cable to the terminal board, be sure to observe the
matching of all color codes.
Connect: RED to RED
RED/WHT to RED/WHT
BLK to BLK
BLK/WHT to BLK/WHT
ORN to ORN
ORN/WHT to ORN/WHT
Only connect one remote to each set of screw terminals.
After completing all connections, check for any shorted
wires. Dress cables flat against the terminal board to allow
space for the master station to be properly secured.
3. Refer to installation instructions packaged with the remote
stations and remote controls for wiring these units.
4. Refer to Figure 3. Use the Wire Matching Chart if you are
retro-fitting a system with the previously used IW-6R cable.
